1. Meaning of Central Tendency

Central tendency means that most data values tend to gather around a central or common value.

In simple words: It shows the middle or typical value around which the data is grouped.

2. How Does Arithmetic Mean Reflect It?

Arithmetic mean gives us one average value for the entire group.

It considers every value in the dataset. It gives a central balance point that represents the group.

Example:

Suppose five students score:

40, 50, 60, 70, 80

The mean is 60. It gives us the average score of the group.

Remember for exams:

• Central tendency means data gathers around a central value.
• Arithmetic mean represents the group through its average.
• It takes every data value into account.
